摘要：The needle assembly holder of the present invention has mounted about its receptacle end a rotatable safety sheath so that irrespective of how the tip of the cannula of the needle assembly is oriented with respect to the holder, the user can nonetheless obtain an unobstructed view of the tip of the cannula by rotating the safety sheath out of her line of sight. Friction drag is provided between the receptacle end of the needle assembly holder and the safety sheath so that the safety sheath would not freely rotate about the needle assembly holder absent a rotation force applied thereagainst.
